.MATERIAL-HANDLING APPARATUS.

Application filed March a1, 1923. Serial No. 629,070.

To all whom it may concern:

Be 1t known that we, EDWIN F. JONES and JOHN A. AULD, citizens of theUnited States, residing atErie, in the county of Erie and .State ofPennsylvania, have invented new and useful Improvements inMaterial-Handling Apparatus, of, which the following is a specification.

This apparatus is particularly designed for measuring materials, such asroad-making materials where an accurate amount is required. Thedesirable way of measuring such material is by filling the measuring binwith slightly more than the exact amount and striking off the excess.Heretofore this excess as it was struck olf has been allowed to fall andaccumulating has required handling. With the present device the materialstruck off by a strike-01f blade is caught and delivered-to themeasuring.

bin so that there is no after-handling or dilli'culty encountered in theoperating or clogging of the strike off device. preferred form thestriking off is accomplished with a movable bin operatingunder a strikeotlj blade. Details and features of the invention will appear from thespecification and claims. The invention is illustrated in theaccompanying drawings as follows Fig. 1 shows a side elevation.

actuating mechanism 14. The car is moved 1 marks the supporting posts,and 2 and 3 storage bins carried by these posts and the usual frames.These storage bins are designed to hold different materials such asgravel and crushed stone and have the discharge openings 4 and 5respectively. A car 6 mounted on wheels 7. is arranged under the storagebins, the wheels operating on tracks 8- so that these cars may be movedto effectjthe striking ofi' operation and carry the material if desiredto a more satisfactory or convenient osition to dump into the trucks.Measuring bins 9 and 10 are usually arranged in pairs of suitable size.These are closed at the bottom-by doors 11 hinged at 12, these doorsbeing connected or operated by a link 13 operated from a. common by acable 15 running around pulleys 16 and 17, the pulleys 17 being carriedby a shaft 18. A gear 19 is mounted on the shaft 18 and operates from apinion20, the pmion In the being operated by means of a crank 21. It

.will be understood that there are a number 91 bins and these areadapted to'dump what 18 commonly called a batch into differentcompartments of the vehicle which is to receive them.

The openings 4.- .md 5 over each of the measuring bins 9 and 10 areclosed by a:

the bins at 28.so that the catcher pockets are arranged at the sides ofthese bins. In

Fig. 3 the one attheleft is shown in a tilting position and the one atthe right in. the

lowered position, the position it assumes in 5 receiving the excessmaterial as it is struck off. by the strike olf blade. Rollers 29 aremounted on the arms 27 and inclined bars 30 are arranged in the path ofthe rollers 29 so that as the bins are moved to a posi== tion under theopenings 4 or 5 the pocket 26 of that bin is tilted as shown at the left7 i of Fig. 3 thus dumping the material which was received by it in thepreceding strike ofi' operation into the bin previous to the deposit ofthe new quantity of material from the storage bin. The pocket-thenremains in the inclined position until the filling of the measuring binwhen the car is again moved to the right as shown in Fig. 3 and as theexcess is struck oil it is carried into this pocket and held there untilthe succeeding operation. The excess material. at the right will, whenthe bin 10 is carried under the opening 5, be tilted thus emptying anymaterial in it into the bin 10 previous to the filling from the opening5. In this way there is no accumulation of this excess and there is afree and accurate action of the strike off blade; means for moving thebin and blade relatively to strike off excess material; and atiltingcatcher actuated with the relative movement of the blade and bin toreturn the overflow to the bin.

3. In a material handling apparatus, the combination of a measuring bin;a strike off mechanism; a tilting pocket at the side of the bin adaptedto catch excess material; and means for actuating the pocket 'to returnthe same to the bin.

t. In a material handling apparatus, the combination of a movablemeasuring bin; a strike ofl' blade operating over the bin; a tiltingcatcher arranged at the side of the set our hands.
